BUFFER non RAILWAY cans..v

Application lel November 12, 1924. Serial No. 749,526.Y

To'aZZ whom t may concer/n.:

Be it known that I, THOMAS ELLIOTT, a citizen of the United States,residing at Cincinnati. in the county of Hamilton and i State of Ohio,have invented certain new and useful Improvements in Buii'ers forRailway Cars, of which the following is a specification, reference beinghad therein to the accompanying drawing. v

This invention relates to railway cars, particularly of the kind used incity and interurban railway operations.

The essential features of -my invention are as follows: l

(l) A form of buffer for obtaining the maximum of strength with theminimum of weight. y

(2) Provision in the buffer for accommodating a couplingpin hole.

(3) `The attachment of the buffer to the sills of the kcar body by meansof a special clip therefor.

(4) Vestibule corner posts secured to hanger plates and these platessecured to the'knee sills of thebody structure, where by in case ofbreakage of the posts, as in collisions or accidents, the'fragments canbe removed, particularly the upper portion of such posts, which usuallygives way first un( er such conditions; and whereby the lower portion ofthe posts, which is secured to the hanger plate lcan then bealsopreadi-v ly removed, after which operations of removal, new postscan be readily installed, as I have ascertained and determined prac"-tically. y

The foregoing and other features to be mentioned in the followingspecification constitute the essentials of my invention.

Inv the accompanying drawings: f

Referring to the drawings, it is to beobserved that the `portion ofFigure 1 embraced in the'right handhalf is not of moment so far as thepresent invention is concerned, but'is merely shown'incident'ally toillustrate the main or center sillsl, the

y9 is a side elevation of the `parts shown in Figure 8, illustrating4the buffer knee Sins 2, and the Step piste These ,I

sills in the portion here referred to, at the left, are in' one part ofthe car.floorstr'ucv-` ture and project beyond under what in pracA ticeis the platform. .At their- 'outer ends Vthe center sills arev equippedwithfmain clips Y 4 which.' are rivetedl to the sills yasby rivets 5.These clips arej shown on an enlarged scale in Figure 6 where it will beseen that flange 4b, and an end ilangel4`. I The flange 4a affordsthepart through :which .the rivets 5 areV extended the. Harige 4"l givesstrength and rigidity tothe clip;.and the flange 4c afords .means forconnecting theclips with the. butter through a bolt and nut? or otherfastening'- device. The center sills passron lbeyond theclips4and. abutagainst the ,genti-al portiony of .the butter, as .shownat Ytheycomprise fa base portion '42%, l'a' side ioc Referring again,specifically, to the buffer, it will be seen vfrom Figures l and 3thatthe middle portion of the middle or intermediate section 23d of thebuffer is extended, formed or bent rearward, as seen at 23e in Figure 3,to give ample space for forming the coupling pin hole 2.3i, as shown invFigures 3 and 4. Thimbles 23g are litted to this hole to receive andguide the pin. The space 23h formed in front of the wall 23d and betweenthe inner horizontal portions of the structure receives the couplinglink through which the pin is to pass.

Thus it will be seen that my improved butler has a crescent shapedoutline so as to taper to small dimensions from the maximum width in thecentral portion; that it has a serpentine cross section to give it greatrigidity and has these provisions for the coupling pin and couplinglink. And also that by reason of' its upper and lower margins it may beand is firmly secured to the adj aeent members of the car structure.

It will be understood that I desire to comprehend within my inventionsuch fmodifications as may be necessary to adapt it to varyingconditions and uses.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent of the UnitedStates, is:

l. A railway car buffer comprising a bar of sheet metal, serpentine incross section, whereby a plurality of ribs kare produced, and providedwith a coupling pin hole extending through the several ribs and having alink recess formed within one of the serpentine bends and intersectingthe pin hole.

2. A railway car buffer comprising a bar of sheet metal of crescentform, and serpentine in cross section, and provided with marginalflanges, a coupling pin hole and a link recess.

B. A railway car buffer comprising a barr of sheet metal of crescentform and serpentine in cross section, and having end projections andupper and lower flanges, and also having a coupling pin hole formed in'its walls with a coupling link Arecess `formed within one of theserpentine bends, the wall constituting such bend being deflectedrearward to form such pocket. j

1l. A railway carbulfer comprising a sheet metal bar having a serpentinecross section. the wall of the inner bend being deflected rearward totorni a coupling link recess.

5. A railway car buller comprising a bar of sheet metal of crescentform, and having end projections, upper and lower ianges and aserpentine cross section, and provided with thimbles constituting acoupling pin hole, and having the wall of the inner fold deliectedrearward to form a recess for a coupling link.

G. In a railway car, the combination with a buffer having an endprojection, of a hanger plate and a vestibule corner post,

and means to secure together such projection, plate and post, and suchpost extending a suitable distance above the-buffer and the platetoconstitute a full post.

7. In a railway car, the combination with a buffer 'having an endprojection, of a hanger plate, ar step plate having an end flange, and avestibule corner post, and means to secure together such projection,hangerv plate-and post, and other means to secure together the hangerplate and such flange of the step plate, the post extending a suitabledistance above such plates to con'- stitute a full post.

8. In a railway car, the combination with a buffer of sheet met-al ofcrescent form and serpentine in cross section, ol hanger platesoverlapping the ends of the buffer, step plates having each an endflange secured to the respective hanger plates, and a vestibule postfitted within each hanger plate and extending upward to form a fullpost, means to secure the ends of the buiier, hanger plates and poststogether, and other means to secure such step plate, flanges and hangerplates together.

9. In a railway car, the combination Vwith a buffer and a vestibule dashboard secured to the buffer, of hanger plates overlapping vportion ofthe butler, such sills being projected into the buer `and having theirends secured to the lower portion of -the buffer, and other clipssecured to the knee sills and the upper portion of the buffer, such kneesills projecting into the buffer and secured to the lower portion of thebuffer.

l1. In a railway car, the combination with aybuler having a serpentinecross section, of main sills extending into the interior of the bufferand secured to the lowerportion thereof, clips secured to the upperportion I of said sills and to the upper part ofthe' buil'er, and kneesills projected into the interior of the buffer and secured to the lowerportion thereof, and other clips securedl to` the endsvof the buffer, astep plate having llO the upper part of such sills and to the uppervportionof the 'buiten 12. In a railway car, the combination with abuffer having serpentine cross section, or" a sill projected into theinterior of the briller and secured to the lower portion thereof, and aclip composed of a base, a'

base flange andan end flange, such base flange being secured totlie'sill and suoli enel flange secured to the upper portion of thebutler.

13. In ak railway car, the-coinbinaton'witli a buffer comprising ztsheet metal bar of crescent form and serpentine in cross section, ofcenter sills and knee sills projecting into the interior oit the butlerand secured thereto below the lower serpent-ine bend, enel clips securedto the upper surfaces of such sills and secured to the buffer above theupper serpentine bend. l

14. In t railway cui', the coinbintion with :L butler comprising e sheetmetal ber of crescent shape and serpentine in cross section, and havingthe inner serpentine bend deflected. to providea recess for a coupling`link, and ham-ng also alcoupllng pin liole, an

upper flange ,and enel projections, of centery and knee sills projectedinto -tlie interior of the buffer and secured thereto, clips secured tothe sills and to portions of the buffer, hanger plates overlapping thebuffer projections, 'step plates having flanges `secured to the hangerplates, and corner vestibule posts litted to the hanger plates andsecured thereto and to the 'bulier projections, `such posts extending'above these connections to constitute e full post.

In testimony wliereor` I elrix my signa-ture.
